I have 3 signature fields on a form that I have just completed. Each of this signature locks each section of the form, but whenever one of this signatures are signed, it shows a message that reads, "Atleast one of the signatures is invalid". I then unchecked the locked all fields check boxes of all 3 variables fields that controlled the fields that need to be locked, and the invalid signatures disappeared, however, the three sections need to be locked when each signature is clicked on. And it works fine, but for this message.
Does anyone knows why it is happening? And what's the solution. I need help.
